DESCRIPTION

EM62GS series TCXOs are packaged in the industry-standard 11.4 x 9.6 x 2.5mm SMD package. With clipped sinewave output, close tolerances are available from ±0.5ppm over 0° to 50°C or ±1ppm over -40° to +85°C. The part has low power consumption. Industry-standard SMD package 11.4 x 9.6 x 2.5mm Close tolerance stabilities from ±0.5ppm over 0° to +50°C ±1ppm over -40 to +85°C Low power consumption RoHS compliant EM62GS - OUTLINES AND DIMENSIONS FREQUENCY STABILITY Frequency Range +3.0 V +5.0 V 10.0MHz to 13MHz 1.3mA 2.0mA 13.1MHz to 20MHz 1.5mA 2.2mA 20.1MHz to 27MHz 2.0mA 2.5mA CURRENT CONSUMPTION Clipped Sinewave, 6 Pad FR4 substrate SMD EM62GS Series SPECIFICATION Product Series Code TCXO: EM62GS VCTCXO: VEM62GS Frequency Range: 10.0MHz to 27.0MHz Output Waveform: Clipped Sinewave Initial Calibration Tolerance**: <±1ppm at 25°C Standard Frequencies: 10.0, 12.80, 13.0, 14.40, and 19.68MHz (Partial list) Operating Temperature Range: See table Frequency Stability vs. Ageing: ±1.0 ppm max. first year vs. Voltage Change: ±0.3 ppm max. ±5% change vs. Load Change: ±0.3 ppm max. ±10% change vs. Reflow: ±1ppm max. for one reflow (Measured after 24 hours) Supply Voltage: +2.8, +3.0 or +5.0Volts ( Specify when ordering) Output Voltage Level: 0.8V p-p minimum Start-up Time: 2ms typical, 5ms max.
